Abstract

original image

R u ready for it yet? The reaction of [Ru(cod)(methallyl)2] with tripodal phosphine ligands of the TRIPHOS-type results in the formation of Ru-trimethylenemethane complexes. Evaluation of their catalytic properties revealed a high activity for hydrogen transfer and C[BOND]O cleavage reactions including the hydrogen-free reductive cleavage of 2-aryloxy-1-arylethanols as model compounds for lignin linkages.
